Sleeves equipped with sensors have been developed to time the actions of factory workers, in order to increase efficiency
In factories where products are mass-produced, it's extremely important to know how long the human workers take to perform certain tasks. This not only allows the pace of the assembly line to be set, but it also allows factory owners to identify time-wasting problems such as superfluous movements, overly frequent tool changes, or impractically-located components. Typically, workers are periodically timed by a stopwatch-wielding supervisor, or using a timer that they start and stop themselves. A new wearable time-keeping system, however, promises more accurate readings.
